Description

Technical Field

[0001] This utility model relates to the field of magnetic rotor technology, and in particular to a magnetic rotor positioning and magnetization device. Background Technology

[0002] In the production process of magnetic rotors, the magnetization process plays a crucial role in the performance of the rotor. When the magnetic rotor is turned, it needs to be demagnetized before turning. After turning, the magnetic rotor is remagnetized. The magnetic field of the magnetic rotor is preset, and the direction of the magnetic field of the remagnetized magnetic rotor must be consistent with the direction of the magnetic field of the magnetic rotor before turning. Therefore, a positioning magnetization device is required.

[0003] A search revealed Chinese Patent Publication No. CN217444184U, which discloses an automatic magnetizing device for magnetizing a rotor assembly. This device includes a support assembly, a first drive assembly and a second drive assembly coaxially mounted on the support assembly at a first preset distance, and a magnetizing assembly. The output end of the first drive assembly is connected to a positioning assembly, and one end of the rotor assembly is positioned on the positioning assembly. The first and second drive assemblies can press against the rotor assembly located between them. The magnetizing assembly is mounted on the first drive assembly and located on the outer periphery of the positioning assembly. The first drive assembly drives the positioning assembly to reciprocate along the axial direction of the rotor assembly through the magnetizing assembly, and the positioning assembly can move the rotor assembly to the magnetizing assembly for magnetization. This automatic magnetizing device can quickly and automatically magnetize a motor rotor.

[0004] In the above-mentioned utility model, one end of the rotor assembly is positioned by the positioning component. However, in actual use, although the positioning component positions one end of the rotor assembly, the lack of positioning control may cause the rotor to have a slight displacement or rotation during the magnetization process, thereby affecting the magnetization effect. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a magnetic rotor positioning and magnetization device, which aims to improve the problem that the lack of positioning control may cause slight displacement or rotation of the rotor during the magnetization process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic rotor positioning and magnetizing device, comprising a base, a worktable fixedly connected to the upper surface of the base, a magnetizing component fixedly connected to the upper surface of the worktable, a magnet disposed inside the magnetizing component, a cylinder fixedly connected to the upper surface of the base, the output end of the cylinder penetrating the worktable and the interior of the magnetizing component and disposed thereon, the outer wall of the placement component slidably connected to the interior of the magnetizing component and the magnet, a rotor body disposed inside the placement component, the outer wall of the rotor body disposed inside the magnetizing component and the magnet, a positioning rod fixedly connected to the upper surface of the placement component, the outer wall of the positioning rod disposed inside the rotor body, a light detection component disposed inside the placement component, a detection hole opened inside the placement component, and a limit component disposed inside the magnetizing component.

[0007] The above technical solution involves a support frame consisting of a base and a worktable, which supports and fixes the cylinder and the magnetizing component. The magnetizing component has a groove inside that matches the outer wall of the magnet, facilitating the installation and removal of the magnet. The output end of the cylinder passes through the worktable and the interior of the magnetizing component and connects to the placement component, allowing the placement component to slide inside the magnetizing component and thus position the rotor body placed inside the magnetizing component. Eight magnets are arranged in a ring to ensure the uniformity of the magnetization process. The protruding part at the top of the placement component matches the concave shape of the rotor body, facilitating the initial positioning of the rotor body.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a limiting frame, the outer wall of which is slidably connected to the inside of the magnetizing component, and a spring is fixedly connected to the outer wall of the limiting frame, the outer wall of which is fixedly connected to the outer wall of the magnetizing component.

[0010] The above technical solution involves a block on the upper surface of the magnetizing component, with the limiting frame sliding inside the block. Simultaneously, the lower outer wall of the limiting frame contacts the upper surface of the magnetizing component, thereby restricting the movement of the limiting frame. The spring force is used to push the limiting frame to the opening of the magnetizing component or to contact the rotor body, thus limiting the movement of the rotor body.

[0011] As a further description of the above technical solution:

[0012] The magnetizing component has an arc-shaped sleeve one and an arc-shaped sleeve two inside, with the outer wall of the arc-shaped sleeve one fitting against the outer wall of the arc-shaped sleeve two.

[0013] Through the above technical solution: the arc-shaped sleeve one and the arc-shaped sleeve two fit together tightly, and the inner walls of the arc-shaped sleeve one and the arc-shaped sleeve two are consistent with the outer wall of the magnetizing component, making it easy to install the arc-shaped sleeve one and the arc-shaped sleeve two in the middle of the magnetizing component.

[0014] As a further description of the above technical solution:

[0015] Both the first and second arc-shaped sleeves are equipped with limiting blocks inside, and the outer wall of the limiting block is set on the outer wall of the magnet.

[0016] The above technical solution ensures the accurate installation of arc-shaped sleeves one and two by using limiting blocks inside the arc-shaped sleeves one and two, with partitions on both sides of each limiting block corresponding to the magnet.

[0017] As a further description of the above technical solution:

[0018] A positioning frame is fixedly connected to the outer wall of the first arc-shaped sleeve, and the outer wall of the positioning frame is located inside the second arc-shaped sleeve.

[0019] The above technical solution involves a positioning frame installed on the outer wall of the first arc-shaped sleeve and a corresponding groove inside the second arc-shaped sleeve, which facilitates the positioning of the connection between the first and second arc-shaped sleeves.

[0020] As a further description of the above technical solution:

[0021] A toothed plate is fixedly connected to the outer wall of the first arc-shaped sleeve, and a fixing block is slidably connected to the outer wall of the toothed plate. The outer wall of the fixing block is fixedly connected to the outer wall of the second arc-shaped sleeve.

[0022] The above technical solution involves fixing the toothed plate by the outer wall of the arc-shaped sleeve, while the interior of the fixing block restricts the movement of the toothed plate.

[0023] As a further description of the above technical solution:

[0024] The fixed block is internally connected to a worm gear, the teeth of which are engaged with a worm wheel, and a connecting rod is fixedly connected internally to the worm wheel.

[0025] The above technical solution allows for easy rotation of the worm by holding the handle at the top of the worm, thereby transmitting power to the worm wheel and connecting rod.

[0026] As a further description of the above technical solution:

[0027] A gear is fixedly connected to the outer wall of the connecting rod, and both ends of the connecting rod are rotatably connected to the inside of the fixed block. The tooth ends of the gear are meshed with the tooth ends of the gear plate.

[0028] The above technical solution involves rotating the connecting rod to drive the gear to rotate, and through the cooperation between the gear and the toothed plate, the toothed plate can move left and right.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the rotor body is precisely positioned and limited by the cooperation between the cylinder, the placement component, the rotor body, the magnet, the positioning rod, the light detection component, the detection hole and the limiting component, so as to ensure the stability of the magnetic rotor during the magnetization process. At the same time, the light detection component automatically judges whether the rotor is correctly placed, which improves the convenience of operation and reduces the occurrence of human error.

[0031] 2. In this utility model, the positioning frame, toothed plate, fixing block, worm, worm wheel, connecting rod and gear cooperate to make the limiting block fit tightly with or release the magnet, so as to realize the installation and disassembly of the magnet. This makes it convenient for operators to disassemble and clean the magnet regularly, ensuring that its surface is not covered by dirt, thereby maintaining the magnetization efficiency and magnetic field stability. At the same time, the detachable design allows damaged magnets to be quickly removed and replaced, improving the safety of the device. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figures 1-3 An embodiment of this utility model provides a magnetic rotor positioning and magnetizing device, including a base 1, a workbench 2 fixedly connected to the upper surface of the base 1, a magnetizing component 3 fixedly connected to the upper surface of the workbench 2, a magnet 7 disposed inside the magnetizing component 3, a cylinder 4 fixedly connected to the upper surface of the base 1, the output end of the cylinder 4 passing through the workbench 2 and the interior of the magnetizing component 3 and disposed thereon 5, the outer wall of the placement component 5 slidably connected to the interior of the magnetizing component 3 and the magnet 7, a rotor body 6 disposed inside the placement component 5, the outer wall of the rotor body 6 disposed inside the magnetizing component 3 and the magnet 7, a positioning rod 8 fixedly connected to the upper surface of the placement component 5, the outer wall of the positioning rod 8 disposed inside the rotor body 6, a light detection component 9 disposed inside the placement component 5, a detection hole 10 opened inside the placement component 5, and a limit component 11 disposed inside the magnetizing component 3.

[0041] Specifically, the magnetizing component 3 has a groove inside for the installation and removal of the magnet 7. The magnet 7 can be connected to a magnetizing device in the prior art, facilitating the magnetization of the rotor body 6. The rotor body 6 is a well-known magnetic rotor. The placement component 5 has two detection holes 10, which are opposite to the rotor body 6. The detection holes 10 are blocked by the rotor body 6 only after the rotor body 6 is correctly placed. The placement component 5 has a light detection component 9, i.e., a light sensor. The detection holes 10 are located above the light sensor, so that the light sensor can detect the light through the detection holes 10 for subsequent processing. The outer wall of the placement component 5 initially positions the rotor body 6, and the positioning rod 8 further positions the rotor body 6. The detection holes 10 are used to detect the correct placement of the rotor body 6. The cylinder 4 is a well-known device, so it will not be described in detail. The output end of the cylinder 4 presses against the placement component 5, thereby supporting the placement of the rotor body 6.

[0042] Reference Figure 2 The limiting component 11 includes a limiting frame 1101, the outer wall of the limiting frame 1101 is slidably connected to the inside of the magnetizing component 3, and a spring 1102 is fixedly connected to the outer wall of the limiting frame 1101, and the outer wall of the spring 1102 is fixedly connected to the outer wall of the magnetizing component 3.

[0043] Specifically, a handle is provided on the outer wall of the limiting frame 1101, and a short rod is provided on the upper surface of the magnetizing component 3, so that the limiting frame 1101 can be moved by holding the handle. When the handle is moved to the front of the short rod, the limiting frame 1101 is rotated and contacts the short rod. The elastic force of the spring 1102 is used to temporarily limit the limiting frame 1101. The limiting frame 1101 is composed of two rods of different sizes and a round block. The round block is used to limit the range of movement of the limiting frame 1101.

[0044] Reference Figure 4 The magnetizing component 3 has an arc-shaped sleeve 12 and an arc-shaped sleeve 13 inside, with the outer wall of the arc-shaped sleeve 12 fitting against the outer wall of the arc-shaped sleeve 13; both the arc-shaped sleeve 12 and the arc-shaped sleeve 13 have a limiting block 14 inside, with the outer wall of the limiting block 14 set on the outer wall of the magnet 7; the outer wall of the arc-shaped sleeve 12 is fixedly connected to a positioning frame 15, with the outer wall of the positioning frame 15 set inside the arc-shaped sleeve 13;

[0045] Specifically, the magnets 7 are set in an arc shape and arranged in a ring, and multiple magnets 7 are separated by partitions. The interior of the arc-shaped sleeve 12 and the arc-shaped sleeve 2 are equipped with limit blocks 14 and partitions, corresponding to the magnets 7, so as to ensure that the limit blocks 14 limit the magnets 7. The limit blocks 14 and partitions are both set to be elastic, and they slide through the partition at the arc-shaped sleeve 2 13 into the partition at the magnetizing component 3, so that the arc-shaped sleeve 12 and the arc-shaped sleeve 2 13 can rotate unexpectedly after installation. The positioning frame 15 is composed of a fixed plate and a short rod, which facilitates the positioning and limiting of the connection between the arc-shaped sleeve 12 and the arc-shaped sleeve 2 13.

[0046] Reference Figure 5 A toothed plate 16 is fixedly connected to the outer wall of the arc-shaped sleeve 12. A fixing block 17 is slidably connected to the outer wall of the toothed plate 16. The outer wall of the fixing block 17 is fixedly connected to the outer wall of the arc-shaped sleeve 13. A worm gear 18 is rotatably connected inside the fixing block 17. A worm wheel 19 is meshed with the tooth end of the worm gear 18. A connecting rod 20 is fixedly connected inside the worm wheel 19. A gear 21 is fixedly connected to the outer wall of the connecting rod 20. Both ends of the connecting rod 20 are rotatably connected to the inside of the fixing block 17. The tooth end of the gear 21 is meshed with the tooth end of the toothed plate 16.

[0047] Specifically, the toothed plate 16 and the fixing block 17 are fixed by the outer walls of both the first arc sleeve 12 and the second arc sleeve 13. When the first arc sleeve 12 and the second arc sleeve 13 are connected, the toothed plate 16 slides into the interior of the fixing block 17 and contacts the gear 21. By rotating the worm 18, the connecting rod 20 and the gear 21 are driven to rotate through the worm wheel 19, thereby driving the toothed plate 16 to move. The connection between the first arc sleeve 12 and the second arc sleeve 13 is self-locked by the characteristics between the worm 18 and the worm wheel 19 to prevent accidental movement.

[0048] Working principle: When using this device, the cylinder 4 drives the placement component 5 to slide inside the magnetizing component 3, leaving space at the opening of the magnetizing component 3. This pulls the limiting frame 1101 to move outwards from the magnetizing component 3, compressing the spring 1102. When the handle of the limiting frame 1101 moves to the short rod on the upper surface of the magnetizing component 3, rotating the limiting frame 1101 temporarily limits its position via the short rod. This places the rotor body 6 at the opening of the magnetizing component 3, allowing it to slide into the interior of the magnetizing component 3 and contact the magnet 7. Rotating the rotor body 6 causes the positioning rod 8 on the upper surface of the placement component 5 to slide inwards. Inside the rotor body 6, and through the cooperation of the light detection element 9 and the detection hole 10, the contact between the lower surface of the rotor body 6 and the detection hole 10 is detected. When the lower surface of the rotor body 6 contacts the detection hole 10 to block it, the rotor body 6 is correctly positioned. The limiting frame 1101 is rotated so that the short rod of the magnetizing element 3 no longer limits the limiting frame 1101. Using the elastic force of the spring 1102, the limiting frames 1101 on both sides move towards the center of the magnetizing element 3, abutting against the spindle of the rotor body 6, and limiting the rotor body 6. Then, through the cooperation of the magnet 7 and the magnetizing device, the rotor body 6 is magnetized.

[0049] By rotating the worm gear 18, the connecting rod 20 is driven to rotate via the worm wheel 19, which in turn drives the gear 21 to rotate. Utilizing the meshing between the toothed plate 16 and the gear 21, the toothed plate 16 is pushed to move inside the fixed block 17. When the tooth tip of the toothed plate 16 leaves the tooth tip of the gear 21, the toothed plate 16 is no longer limited, and the arc-shaped sleeve 12 and arc-shaped sleeve 23 move to the outside of the magnetizing component 3, thereby allowing the arc-shaped sleeve 12 and arc-shaped sleeve 23 to slide out of the interior of the magnetizing component 3, no longer limiting the magnet 7, making it convenient to remove the magnet 7 for cleaning. During use, this device not only accurately positions the rotor body 6 but also enables the installation and removal of the magnet 7.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
